Izvi zvigadziriso zvekugadzirisa zvakagadzirirwa kuchengetedza mapfupa madiki, zvimedu zvemapfupa, uye osteotomies munzvimbo. Vanopa kugadzikana panguva yekuporesa uye kukurudzira kurongeka kwakakodzera. Nekudaro, zvakakosha kuti uzive kuti hazvina kukodzera kushandiswa mukukanganisa matishu akapfava kana kugadzirisa mune nyoro. Izvo zvakakosha kutevedzera zvakatarisirwa kushandiswa uye kurudziro inopihwa nenyanzvi dzekurapa kune yakakwana uye yakachengeteka mhedzisiro.
